Blue Jay Highbush Blueberry (Vaccinium corymbosum 'Blue Jay') Blue Jay Highbush Blueberry is a vigorous, upright northern highbush selection valued for reliable midseason crops of firm, light blue berries; its dense, multi-stem habit, white spring flowers, and red to orange fall color provide edible beauty for sunny gardens and large containers. Distinctive Features Medium to large, mildly sweet berries with good firmness and small dry scar form in large clusters; plants are cold-hardy, productive, and noted for balanced flavor and strong disease resistance when sited correctly. Growing Conditions Sun Exposure: Full sun for highest yield and sugar. Soil: Moist, well-drained, organic-rich, acidic soil. Water: Keep evenly moist, especially from bloom through harvest. USDA Hardiness Zones: 4 to 7. Mature Size: Typically 5 to 7 ft tall and 4 to 6 ft wide. Bloom Time: Spring; fruit ripens midseason, often early to mid summer. Soil pH: 4.5 to 5.5 for best performance. Ideal Uses Focal Point: White spring bloom and colorful fall foliage frame patios and entries. Edible Hedge: Multi-stem form creates a productive screen. Wildlife Support: Flowers feed pollinators; berries attract birds. Large Containers: Thrives in acid media with regular feeding and water. Low Maintenance Care Watering: Deeply water when the top 1 in is dry; avoid drought during fruit set. Pruning: In late winter, remove weak wood and oldest canes after year 4 to 5 to renew growth. Fertilizing: Feed in early spring with an acid-forming fertilizer such as ammonium sulfate; repeat lightly after bloom if needed. Mulching: 2 to 4 in of pine bark or needles to conserve moisture and maintain acidity. Notes: Self-fertile but heavier crops with a second midseason cultivar; net plants to deter birds and avoid alkaline soils to prevent chlorosis. Why Choose Blue Jay Highbush Blueberry?
